Note:

These binoculars feature a central focusing knob and do not have a separate eyepiece (diopter) adjustment. This is by design: the optical system is configured so that both optical channels track focus together, keeping the left and right images balanced without the need for individual fine adjustment.

Technically, this is achieved through a coupled focusing mechanism that moves the internal focusing elements (or objective/ocular group, depending on the design) in both barrels simultaneously, maintaining the same focal shift on each side. This approach reduces mechanical complexity, helps preserve collimation stability (alignment between the two optical paths), and can improve durability by eliminating an additional moving/adjustable eyepiece assembly.

In practical use, the binoculars are focused using the central wheel only, and the image remains evenly focused for both eyes under normal viewing conditions.
